Early life and education

Dalton was born into a Quaker family of traders; his grandfather Jonathan Dalton was a shoemaker, and his father, Joseph, was a weaver. Joseph married Deborah Greenup in 1755, also from a prosperous local Quaker family. Dalton was the youngest of three of their children who survived into adulthood. He attended John Fletcher's Quaker language school in Eaglesfield. When John was only 12, Fletcher transferred the school to John's older brother, Jonathan, who called younger Dalton to help with the teaching. Two years later the brothers purchased a school in Kendal, where they taught about 60 students, some of whom were students.

As a teacher, Dalton drew on the experience of two important counselors: Elihu Robinson, a Quaker gentleman who loved the methods and methods of science at Eaglesfield, and John Gough, a mathematician and archaeologist at Kendal. From these men John received mathematical, Greek, and Latin origins. Robinson and Gough were also amateur astronomers in the Lake Region, and to them Dalton gained valuable experience in the construction and operation of meteorologic instruments and the command to keep daily weather records. Dalton maintained a deep interest in meteorologic measurements throughout his life.

Early scientific work

In 1793 Dalton moved to Manchester to teach mathematics at the opposition school, New College. He took with him proof of his first book, a collection of meteorologic articles based on his observations, and his friends John Gough and Peter Crosthwaite. This work, Meteorological Observations and Essays, was published in 1793. It did not create chaos in the beginning but contained original ideas, as well as Dalton's highly developed articles, which marked the transformation of meteorology from the subject of traditional history to the deep pursuit of science.

Born and raised in the mountainous Lake County of England, Dalton had a wonderful place to watch various weather events. He supported the idea, in contrast with modern theory, that the atmosphere was a mixture of about 80 percent nitrogen and 20 percent oxygen instead of compounds. He measured the force of air evaporating on water vapor and its relative pressure and temperature. He described partial pressure in terms of natural law when all components of a gas mixture exert the same pressure that they would have if they were the only available gas. One of Dalton's contemporaries, British scientist John Frederic Daniell, later praised him as “the father of meteorology.”

Shortly after his arrival in Manchester, Dalton was elected a member of the Manchester Literary and Philosophical Society. His first contribution to this community was an explanation of the character he had acquired in his vision with his brother. This paper was the first book on color blindness, later known as Daltonism.

To this day, Dalton's most influential work on the chemical field was his atomic theory. Attempts to trace Dalton's precision to this idea have been in vain; even Dalton's memory of the story is incomplete. He based his view of partial pressure on the idea that like atoms in a mixture of gases, the atoms of the atom seem to react indifferently to one another. This hypothesis explained why each gas in the mixture behaves independently. Although this theory later proved to be erroneous, it served a useful purpose in allowing him to put an end to this notion, held by many ancient atomic philosophers from the Greek philosopher Democritus to the 18th-century mathematician and astronomer Ruggero Giuseppe Boscovich, that atoms of all kinds. things are the same. Dalton argued that the atoms of various elements vary in size and size, and this charge is a fundamental part of his atomic theory. His assertion that each element had its own atomic nature was at odds with those who believed that having too many different basic particles could undermine the simplicity of nature, but Dalton dismissed their arguments as meaningless. Instead, he focused on determining the related masses of each different type of atom, a process that can be accomplished, he said, only by considering the number of atoms of each element present in different chemicals. Although Dalton had taught chemistry for several years, he had not yet done any real research in the field.

In a memorandum read to the Manchester Literary and Philosophical Society on October 21, 1803, he stated: “The investigation into the relative weight of body particles is, to the best of my knowledge, entirely new.
